Atomic force microscopy in food preservation research: New insights to overcome spoilage issues

The next degree of food security is required due to the fast-growing human inhabitants together with the elevated consciousness of wholesome existence. Currently, a big proportion of food is spoiled throughout storage and processing due to enzymes and microbial exercise, inflicting large financial losses to each producers and shoppers. Atomic force microscopy (AFM), as a robust scanning probe microscopy, has been efficiently and broadly used in food preservation analysis. This approach permits a non-invasive examination of food merchandise, offering high-resolution photos of floor construction and particular person polymers in addition to the bodily properties and adhesion of single molecules. In this paper, detailed purposes of AFM in food preservation are reviewed.

AFM has been used to present complete info in food preservation by evaluating the spoilage with its associated construction modification. By using AFM imaging and force measurement operate, the principle mechanisms concerned in the lack of food high quality and preservation applied sciences improvement might be additional elucidated. It can also be able to exploring the actions of enzymes and microbes in influencing the standard of food merchandise throughout storage. AFM supplies complete options to overcome spoilage issues with its versatile capabilities and high-throughput outcomes. Further analysis and improvement of this novel approach in order to resolve built-in issues in food preservation are obligatory.

Simultaneous imaging of complementary absorption and fluorescence contrasts with excessive spatial decision is beneficial for biomedical research. However, standard dual-modal photoacoustic (PA) and fluorescence imaging methods require using acoustic coupling media due to the contact operation of PA imaging, which causes issues and complicates the process in sure purposes corresponding to cell imaging and ophthalmic imaging. We current a novel dual-modal imaging system which mixes non-contact PA microscopy (PAM) based mostly on PA distant sensing and fluorescence microscopy (FLM) into one platform.

Assessment of the pressure depth sensitivity of Moiré sampling Scanning Transmission Electron Microscopy Geometrical Phase Analysis via a comparability with Dark-Field Electron Holography

In this examine, the Moiré sampling Scanning Transmission Electron Microscopy Geometrical Phase Analysis (or STEM Moiré GPA) pressure characterization methodology is in contrast to the well-established Dark-Field Electron Holography approach on a skinny movie stack grown by Molecular Beam Epitaxy. While experimental knowledge obtained with the 2 methods are, total, in good qualitative settlement, small statistically related variations are domestically noticed between the 2 strategies.

The outcomes obtained from each methods are additional confronted with Finite Element Method (FEM) mechanical simulations modeling the pressure rest phenomena from a skinny lamella. The FEM simulation highlights a non-uniform deformation area alongside the beam propagation path with a better deformation degree close to the floor of the lamella in contrast to the middle of the identical lamella. The system permits excessive lateral decision of two and a couple of.7 µm for PAM and FLM modes, respectively. In vivo imaging of a zebrafish larva injected with a rhodamine B answer is demonstrated, with PAM visualizing the pigment and FLM revealing the injected rhodamine B.

The center-surface pressure variations obtained from modeling are per the experimentally derived variations accounting for the truth that the SMG methodology is delicate to the pressure state of the floor of the lamella with a really slim depth-of-field, and the DFEH approach is measuring the pressure state of the middle of the identical lamella averaging over a big part of the thickness. The depth-of-field distinction between each strategies might be fairly associated to their respective distinction mechanisms (STEM vs Conventional Transmission Electron Microscopy). As the SMG methodology is utilizing a convergent probe, the slim depth-of-field could be used to sense the deformation area over completely different sections of the lamella utilizing the defocus and probably retrieve the three-dimensional pressure area.

Visualization of probiotics by way of epifluorescence microscopy and fluorescence in situ hybridization (FISH)

Aerobic plate counts, the usual for bacterial enumeration in the probiotic trade, might be biased in the direction of fast-growing organisms that replicate on artificial media and might considerably underestimate complete bacterial abundance. Culture-independent approaches corresponding to fluorescence in situ hybridization (FISH) maintain promise as a way to quickly and precisely enumerate micro organism in probiotic merchandise. In addition, FISH has the potential to extra precisely signify bacterial progress dynamics in the atmosphere in which merchandise are utilized with out imposing extra progress constraints which are required for enumeration by way of plate counts.
In this examine, we designed and optimized three new FISH probes to visualize and quantify Bacillus amyloliquefaciens, Bacillus pumilus, and Bacillus licheniformis inside probiotic merchandise. Microscopy-based estimates have been constant or greater than label claims for Pediococcus acidilactici, Pediococcus pentosaceus, Lactobacillus plantarum, Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus licheniformis and Bacillus pumilus in each a direct fed microbial (DFM) product in addition to a crop microbial biostimulant (CMB) product. Quantification with FISH after a germination experiment revealed the potential for this method to be used after utility of the product
